Answer:

The area of CD is 17.71
in^(2)

Explanation:

Radius of the disk =
2(3)/(8) = 2.375 in

Since CD is in shape of circle So area of the circle is given by

$A = \pi r^(2)$

Put the value of radius in above equation we get

A = 3.14 ×
2.375^(2)

A = 17.71
in^(2)

Therefore the area of CD is 17.71
in^(2)
